slow typing response when MP is open (1 Viewer)

[Sacamantecas]

I use two screens connected to my computer, I usually see movies and stuff while working.

But when MP is open, typing it's really slow on the other screen, there is any solution?

I have a 9600GT, a 8200 intel processor and 2 GB memory

Well, I have just downloaded the new release, RC2, and it seems to work fine now.
